end(3C)                                                   end(3C)



     NAME
          end, etext, edata - last locations in program

     SYNOPSIS
          extern end;
          extern etext;
          extern edata;

     DESCRIPTION
          These names refer neither to routines nor to locations with
          interesting contents.  The address of etext is the first
          address above the program text, edata above the initialized
          data region, and end above the uninitialized data region.

          When execution begins, the program break (the first location
          beyond the data) coincides with end, but the program break
          may be reset by the routines of brk(2), malloc(3C), standard
          input/output (stdio(3S)), the profile (-p) option of cc(1),
          and so on.  Thus, the current value of the program break
          should be determined by sbrk(0) (see brk(2)).

          These symbols are accessible from assembly language if it is
          remembered that they should be prefixed by .
